N-screen 은 여러 단말을 통한 콘텐츠 소비형 서비스로써 이용자 환경과 요구사항에 반응하여 연속성을 가지고 이용자가 원하는 단말을 통해 제공될 수 있다. 자신이 가지고 있는 다양한 단말만 아니라 인증을 거친 다른 사용자가 가진 단말에도 N-screen 을 제공할 수 있다. 서로 다른 서비스 이용자 간 N-screen 을 제공하기 위한 플랫폼으로써 웹 플랫폼을 이용할 수 있다. 웹은 N-screen 을 제공하기 위해 가장 우선시 되는 요구사항인 플랫폼의 통합을 이끌어 낼 수 있으며 서비스 플랫폼과 협업을 통해 서비스 이용자의 요구사항을 만족시키고 동시에 Community 융합을 통해 전혀 새로운 서비스로 제공될 수 있다. 이에 본 논문에서는 웹 기반 N-screen 환경에서 Community 서비스 제공을 위한 서비스 제어기능 모델을 제안하고 그에 따른 서비스 시나리오를 설명한다.

The appearance and evolution of cloud service is potentially one of the major advances in information and communication technology. However, it is necessary to identify and understand the various issues of cloud service, both from the perspectives of the providers and the consumers of it. While a lot of studies such as cloud business model, profit model and technology itself are currently taking place in cloud service considering provider's aspects, there are a few researches dealing with cloud service user's aspects. This paper presents the user behavior analysis focused on SaaS users and discusses the development strategy of SaaS service based on the results of user behavior analysis. In order to analyze the user behavior, we surveyed SaaS users divided into two groups such as present and future user groups. Eventually, we proposed the SaaS prospects, development strategy and policy issues based on user behavior analysis.

The purpose of this study is to design and develop a alternative material recommendation system using automatic classification, based on user preference. Details of usage data by users from DREAM was analysed in order to develop the way of a method on selecting proper alternative material, and then the data by user preference were allocated under each category of 10 KDC categories. The keyword, selected from the title of users' usage data from a certain period of time, were divided into 10 subject categories and ranked by the order of frequency of appearance. Books including high frequency of the keyword in title can be selected as a preferred target for producing alternative materials. Lastly, a dynamic linkage for sharing usage data among National Library for the Disabled and other libraries is proposed to produce more proper alternative materials, based on user preference.

As the use of shared electric kickboards is rapidly increasing, there are many cases of illegal parking of shared mobility. In order to solve this problem, local governments are taking measures such as towing illegally parked shared electric kickboards, but user management is not considered and the methods are inefficient. Accordingly, in this paper, we propose a blockchain-based shared electric kickboard user management model. The shared electric kickboard is equipped with a camera sensor and GPS that can check the parking status, and when the user ends the use of the shared electric kickboard, information on the parking status is collected through the installed sensors and the shared electric kickboard company You can check if the user has parked correctly. In addition, trust points are given according to the user's parking history and incentives are provided according to the trust points, inducing users to return the shared evangelism kickboard correctly. The information is shared through the consortium blockchain in which shared electric kickboard companies participate, enabling integrated user management of shared electric kickboard companies.

PDA model is new collection development method not only corresponding user's demand, but also expensing acquisition budget effectively. In the PDA model, when the trigger that indicates user's demand reaches up to treshold, e-book is automatically purchased without librarian's interrogation. This study examines concept, basic principles, and current condition of operation about PDA and finds a way that could applicate to Korean university library foreign E-book consortium. Current model of university library e-book acquisition pursuit reduction of budget and utility value, but the selected collection is not based on user's demand. Therefore, it could be considerable to apply PDA or evidence based purchase model to foreign e-book acquisition consortium.

The purpose of this study is to establish the new concept of "user-centered" suitable for currentdigital environment and to derive system design factors necessary for user-centered informationretrieval system design of the university libraries.The result of this study can be summarized as follows .First, the concept of 'users-centered' in digital environment where the supporting role ofintermediaries is growing bigger than before in the interaction with remote information retrievalsystem can be defined as the new concept of 'expansion of knowledge'.Second, 6 kinds of system design factors derived for user-centered information retrievalsystem design of the university librariesf the university libraries.

By measuring satisfaction index of the users of Information System, it is possible not only to estimate ROI(Return on Investment) but also to draw the device for the efficiency and improvement of the System. This study tries to give User Satisfaction Index Model for the System, and present operators and managers of the system with the method for improving satisfaction and efficiency by measuring the User Satisfaction Index of representative information systems. For this, the survey was carried out for the representative information systems. On the basis of the analysis, Satisfaction Index was drawn and through Matrix Analysis, the strategy for system improvement was derived.

The purpose of this study is to derive system design factors and to analyze user needs of university library for design of user-centered information retrieval system. The result of this study can be summarized as follows: First, the concept of 'users-centered' in digital environment where the supporting role of intermediaries is growing bigger than before in the interaction with remote information retrieval system can be defined as the new concept of 'expansion of knowledge'. Second, 6 kinds of system design factors derived for user-centered information retrieval system design of the university libraries. Third, The user needs that examined and analyzed through the questionnaires made by user-centered approach according to the design factors should be considered for system design.

The purpose of this study is to find out implications which can be useful for the development of user empowerment and involvement in Korean disability services. Suggested implications are based on the earlier studies about the concept and areas of user involvement. In the theoretical review, this study compared several terminologies related to user involvement. For the depth explanation, this study described wide range of earlier studies. In addition to these descriptions, this study is exploring to show integrated theoretical framework including diverse areas, major initiatives, participation levels, models of purpose on user involvement. And to grasp ostensive understanding on specific mechanisms on participation practice, this study discussed various issues on basic assumptions, areas of involvement and supportive alternatives. Based on these theoretical examination, this study introduced concrete tasks related to policy, service organization, professional education and research to activate user participation in Korean disability services.
